HECTOR KIBELE, 0F BLUFFTON, OHIO, ASSIGNOR TO THE JDILLER MANUFACTURING COMPANY, 0F BLUFFTON, OHIO, A CORPORATION OF OHIO.

FIRELESS COOKER.

Application filed May 25, 1912.

To all whom t may concern Be it known that l, HECTOR KIBELE, a citizen of the United States, residing at Bluffton, in the county of Allen and State of 0hio, have invented certain new and useful Improvements in Fireless Cookers, of lwhich the following is a specification, reference being had therein to the accompanying drawing.

rlhis invention relates to tireless cookers and the object of the invention is to pro vide means whereby a tight joint may be secured between the body portion of the cooker and the closure and whereby this joint may be maintained tight throughout the life of the cooker.

lTo this end it is a further object of the invention to provide the cooking compartl ment or receptacle with a seat adapted to be engaged by part carried by the closure, to form the joint, and to provide means whereby the cooking compartment may be moved to adjust the seat relatively to the closed position of the lid or closure.

In the accompanying drawing Figure l is a vertical section taken centrally through a cooker embodying my invention; and Fig. 2 is a vertical section taken through the upper part of the cooker.

In the drawing I have illustrated one embodiment of the invention and have shown the same as comprising a body portion and a lidmovably mounted thereon. The body portion is shown as comprising a frame or casing' consisting of upper frame members l having secured thereto side members 2 of sheet metal, the bottom of the casing being closed by a bottom piece, 3, of sheet metal, which is here shown as provided. with lips to receive the lower ends 0f the side walls 2. Mounted within the casing is a food compartment or receptacle 4 which is separated from the bottom and side walls of the casing by a space which is filled with suitable insulating material. rllhe closure or lid is shown at 14 and may be mounted on the body portion 1 in any suitable manner, as by hinging one edge of 'it to one of the frame members l in the usual manner. The body portion of the cooker is provided with a seat and the lid or closure is provided with a part adapted, when the lid is in its closed position, to engage this seat and form a tight joint which will effectually prevent the escape Specification of Letters Patent.

of steam or other vapors. The lid is here shown as provided with a relief port 5 which, in practice, is provided with a valve to control the escape of steam from the food compartment. This valve forms no part of the present invention and need not be here shown. In the construction of the device here shown the food compartment or receptacle 4 is provided at its open edge, which, in the present instance, is its upper edge, with a laterally extending flange (3 rigidly secured `to and in effect forming a part of the receptacle and I,having its outer edge secured to the frame members l and forming the upper retaining wall to confine the insulating material. This fiange is preferably shaped to form a seat adapted to be engaged by a depending portion 7 carried by the lid 2 and shaped to fit snugly within the seat formed by the iange 6 and form a tight joint between the body portion of the cooker and the closure therefor.

In assembling the cooker difliculty is experienced in securing the exact adjustment of the parts to render the joint perfectly tight, and further, after the device has been in use for a period of time it not infrequently happens that the flange G will become depressed or sag in such a way as to loosen the joint. To enable a tight joint to be secured in the first instance with a minimum of trouble and to maintain this joint tight throughout the life of the cooker' I have provided means for adjusting one of the j oint-forming members relatively to the other. In the form here shown the food compartment 4: is capable of bodily movement toward and away from the normal position of the closure, this movement being permitted by the flexibility of the flange 6 and serving to adjust the seat formed by this fiange relatively to the closed position of the lid. This movement may be imparted to the compartment or receptacle in any suitable manner. That here shown consists in mounting `the receptacle upon a supporting member, such as a transverse bar 8, which bar is so connected with the frame members 1 that it can be caused to move toward or away from the same. One very etticient method of accomplishing this movement is by securing a pair of rods 9 to the frame members and allowing these rods to extend downward along the side members 2 of the casing thraugh the end portions of the supporting bar 8 and through the bottom wall 3 of the casing where they may be provided with nuts 10. Obviously, when the nuts 10 are tightened upon the ends of the rods the bar 8 will be forced upward and will carry with it the compartment or receptacle 4, thus moving. the seat formed by the flange 5 toward the closed position of the lid and serving totighten the joint.

The tightening of the nuts on the rods will, of course, cause the flexible bottom 3 to bend or buckle'and will, to a slight extent laterally displace the openings through which the ends of the rods extend, but these openings, as shown in the drawings, are of ample size to permit this displacement Without causing therodsrto bind or to be laterally displaced." Consequently, the rods will remain in their proper positions relatively to the transverse bar 8 and this bar will move freely upon the ro'ds. lVliile it is only necessary that the openings in tliis lbar should be sufficiently large to permit of a free movement longitudinally of the rods, in the ordinary manufacture of this device, the openings in the bar are made somewhat larger than the diameter of the rods t0 fa: cilitate the assembling of the device and owing to this slightly larger diameter of the openings any slight lateral displacement of the rods will not cause the bar to bind. The space about the bar 8 and between the bottom of the receptacle or compartment 4 and the bottom wall 3 of the casing may be filled withy insulating material and suitable insulating material may be interposed between the bottom of the compartment and the supporting bar, as indicated at 11.

It will be apparent from the foregoing description that I have provided a very efficient method of securing and maintaining a tight joint between the body portion of the cooker and the closure therefor and have provided means whereby one of the mem-` bers forming the joint can be adjusted from the exterior of the casing to tighten the joint.

I wish it to be understood that I consider myself the first to provide adjusting means for this purpose, in a tireless cooker, and I further wish it to be understood that while I have shown and described one embodiment of the invention, this has been chosen for the' purpose of illustration and I do not wish to be limited to the detailsof construction shown and described, for obvious modi tications will occur to a person skilled in the art,
